摘要：Extension conjecture states that if a simple module over an artin algebra has nonzero first self-extension group then it has nonzero i-th self-extension group for infinitely many positive integers i. In this talk, I shall introduce the extension conjecture, and show that it holds true for finite-dimensional elementary algebras over a field, particularly, for finite-dimensional algebras over an algebraically closed field.
